Physical properties of urine

Color, Odor, and transparency

  1. Examine the urine specimen for color, odor, and transparency
  2. Record your observation

Specific gravity

  1. Weigh a 100-mL graduated cylinder
  2. Fill the graduated cylinder with 50mL of urine sample and weigh.
  3. Get the weight of the urine by subtracting the weight of the empty graduated cylinder from the weight of the graduated cylinder with the urine sample
  4. Divide the weight of urine by volume. The value obtained will be your urine density. Assuming that the density of water is 1 g/mL, the density of the urine is equal to its specific gravity.

pH

  1. Using a pH paper or a pH meter, determine the pH of the urine
